ATTACHMENT FOR LAMP-GI-IIIIlllIIH LYQ.

; Specification of Letters Patent. I

Application filed January 15, 1910. Serial No. 638,299. f

Be it known that I, CALHOUN D. Hnno'n'n, citizen of the UnitedStates,-.residin Draper, in the county of Pulaskiand tate of Virginia,have invented certain new and useful Improvements in Attachments forLamp-Chimneys, of which the following is a Specification.

My invention relates to the burners and chimneys of oil lam s, andparticularly to a device adapted to e,supported above the lamp'so as todirect the heated air ,and smoke toward t e center of the space inclosedWithin the chimney, the object of the invention being to prevent smokinof the I reaking because of the heat of the flame, to prevent thelightbeing extinguished by down drafts,

and to permit the flame to. be turned up so that the lamp will givebetter light without danger of smoking.

The invention consists essentially in a conical hood supported withinthe lamp chimney and above the burner of the same, the small end of thehood being located upward, this hood acting to direct the heated air andthe products of combustion toward the centerof the space inclosed by thechimney and away from the chimne itself, the hood also acting tominimize own drafts and thus lessen the chance of the flame being blownout.

A still further object of the invention, in one of its forms ascontemplated by me, is to minimize the chance of the chimney beingaccidentally disengaged from the burner or chimney base- For a fullunderstanding of the invention -and the merits thereof, and to acquire aknowledge of the details of constrdction, reference is to be had to.-the following description and accompanying-drawings, in which:

Figure 1 is a longitudinal section of a lamp chimney, the burner beingshown in elevation, with my invention shown in lace therein; Fi 2 is aperspective view 0 the conical hoo detache from the burner; Fig.

i ,3 is a side elevation of a burner, the chimney thereon being shown insection, with another form of my inventlon applied thereto; and, Fig.4is a fragmentary perspective showing the ping for supporting the hoodupon the burn r base.

Patented J Referring to Figsll and 2, in which the simplest form ofmyinvention is shown, designates aburner of any usualcharacter,

and B the chimney-thereon, this'chimn'ey" being formed with'the usualenlarged portion I; and the upper contracted neck I). My inventionconsists in the use within' the chimneyof an inverted conical hood2which is smaller than the chimney itself and is therefore. 'spacedtherefr'om', 7.-the upper and lower ends of lthis' hood being open.. Thehood is supportcd'above the' burner in any suitable manner. 'As shown inthe. figures above referred to, the hood, which-maybe of metal or of anyrefractory substance, is provided with the supporting strips 3; whichare attached to they hood in an suitable manner, the upper ends of thestrips being bent outward, as at 4, to engage witlfthe lamp chimneybelow the neck 'b-. thereof while the lower ends of the strips extendoutward in line with the conical face of the hood and at their lowerends are sli ht ly bent outward so as to engage the lam ney in theenlarged portion 1) thereo which a is below that supporting strips 4 arepreferably resilient so that the hood 2 inay be placed within any partof the bulge where the lamp chimney commences to'contract. The' ordinarysized lamp chimney and will be held therein by the resilience of thestrips 4. As shown, the strips 4 are riveted to the hood 2, but anydesired means'of attaching I the strips may be used.

In Figs. 3 and i I show another form of my invention which, while itcontains the essential features present in the form pr'e-' viouslydescribed, also provides means for preventin the detachment of thechimney from the urner. In these figures, A designates the burner and Bthe chimney. 7 designates the coriical inverted hood, preferably ofrefractory material, the upperend of this hood being formed with acontracted neck 8. The lower end of the hood is attached to resilientsupporting strips 9 formin standards which are curved outwardjo tapproximately the outward bulg'e or curve of the lamp chimney, the lowerends of the stri s being engaged with or mounted upon t e I base of theburner A. Preferably, in order to detachably support the strips 9',uponthe burner A, I provide the lowerends of the strips 9 with the ring 10which is of suflicient size to fitupon the base of the burner rEreferably made of material having a re ecting inner surface, as such asurface acts to give an increased light.

The advantages of my invention are as follows: The inverted cone suported above the flame and in spaced re ation to the chimney, preventsthe smoking or smutting of the chimney. This is effected by reason ofthe hood being of sufficient size to entirely cover theflame. The heatedproducts of combustion, however, rising from the flame, are directedbythe hood inward so as to form a heated column of air rising through thecenter of the chimney and not coming in contact with the chimney'itself.By reason of this fact .that the heated products of combustion are ke taway from the chimney, the light may, e turned higher than with theordinarychimney, andthus a larger flame may be used, resulting in abetter light.

My attachment also decreases very materially the breakage of chimneys,due to-the heat of the flame, by reason of the heat being directedtoward the center of the chimney and being kept away from the walls ofthe chimney, thus the chimney remains cool at all times. Further, thecone prevents the extinguishing of the light by reason of strong gustsof air forced down the chimney, as when the lamp is being carried out ofdoors, or in laces where there is a strong draft. It will 0 obvious thata down draft of air will be diverted toward the chimney, and onl arelatively small proportion will pass do n through the central openingand strike the flame.

'With the construction shown in Fig. 3, an additional advantage isgained, in that the attachment securesthe chimney t0 the burner in sucha manner that the chimney cannot be displaced by any jar or blow. Thisis effected by :means of the standards 9 which, bulging outwardas theydo, correspond to the outward curve of the chimney,

and by reason of the spring therein, secure the chimney firmly in place,at the same time permitting thechimney to be lifted in order 'to lightthe lamp.

\Vhile I have shown what I believe to be the essential features of mydevice, and the best form thereof, I do not wish to be limited to thesedetailsof construction, as it is obvious that the principles of theinvention might be embodied in a number of differing forms.

It will be obvious also that the device is adapted for use on all kindsof kerosene lamps and lanterns using chimneys, and that the attachmentmay be so shaped as to be adapted for use in any shape of chimney.

While I have described the hoods 2 and 7 as being made of metal and asprefer- .ably having a reflecting inner surface, I

wish it understood that may use any suitable material for this purpose,this material being preferably refractory, and that I may parentrefractory material.

Having thus. described the invention, what use for this purpose mica orother transfrom the lower portion of the hood and adapted to engage theinside face of a lamp chimney, said'strips acting to support the hoodandcenter the same. I

2. The combination with a lamp burner, of a conical hood 'open at bothends, and downwardly extending strips attached to the margin of the-hoodand at their lower ends engaging with. the burner to support the hoodthereon, the intermediate portion of the strips being outwardly bowedfor frictional contact with the inner face of the chimney along theirwhole extent.

3. An attachment for lamps, comprising a ring adapted to fit upon thebase of a lamp burnerfclznnps on said ring, for engaging said basc,upwardly extending supports on the ring and a conical hood mounted onthe upper end of the supports.

4." An attachment for lamps, comprising a ring adapted to be attached tothe. base of a lamp burner, outwardly extending tongues on the ringadaptedto be bent beneath the base of the burner, supports on the upperends of the supports, the hood being open at both ends.

5. An attachment for lamps, comprising a ring adapted to fit over thebase of a burner-and having clamps for engaging said base, upwardlyextending supports on the the ring, and a conical hood mounted on on theupper end of said hood, said supports being resilient and outwardlycurved to fit against the inner face of the chimney;

6. An attachment'for lamp burners comprising outwardly bowed, resilientmembers adapted to have frictional engagement with the inside face of alamp chimney, said members at their lower ends being formed withclamping tongues returned on them- 10 selves to engage. with the edge ofthe base In testimony whereof I affix my signature in presence of twowitnesses.
